XR inner-grooved aluminum alloy tube (Alloy grade: 3003 or 3103, etc.)
Aluminum ingots are extruded, drawn, inner grooved to made into tubes. XR's aluminum tube has good ductility, and the inner helical fin height of 0.05-0.30mm ensures the excellent heat conduction performance required by the air-conditioning heat exchanger, thereby greatly reduced the current air-conditioning production cost.
All tubes can be customized based on your requests on size and fin shape.
